Fire Service to trial AVL

The Fire Service are to trial a GPS based Automatic Vehicle Location (AVL) system to allow the closed appliance to be dispatched. They also want to provide pocket PC's to provide data in the field. Both systems will make use of one of the mobile networks.

Ambulance New Zealand is also looking at similar trials.

The Police had similar systems as a part of the ill fated Incis project, but are now also trialing AVL and mobile data technologies in Auckland. Police to boost frontline technology

Post JOTA

JOTA weekend went off pretty well, a lot of setting up and running around to get it all going, and all seemed to have had a good time.

We had scouts build two HF antenna masts using their pioneering skills.
We were active on HF, VHF and UHF. We had an ATV station running at various times. We also had an APRS station and tracker running, we made use of a portable EPIRP direction finder to demonstrate ARDF type activities, and we had JOTI available. (Although attempts to get an 802.11 Wireless LAN connection back to my place was unsuccessful we had 2 computers on JOTI via my cell)

We had around 25 Cubs and Scouts, mostly from Holmes Park, but a few from other Groups in the District, through the weekend.

GPS Reliability fragile?

As Trimble has stated "GPS - The 9th Utility". Many aspects of society now rely on GPS signals, and at present the US Government/Military is responsible for the system, its upkeep and reliability. If the update of the satellites does not keep up with, or ahead of, failures of the now aging devices then the system could become compromised.

The Russian system essential failed due to a lack of funds to maintain it.

The new European Galileo system is still some way off.

MED approves UWB imports

The MED Radio Spectrum Management group will license on a case-by-case basis Ultra Wide Band systems operating at 24GHz. These systems can be used for short range high speed data applications, and also by cars as a anti-collision radar systems.

They can also be used for USAR applications to detect casualties buried under rubble.

There is a potential for interference from these devices to other radio equipment.

Is it being over hyped by the Media? Bird Flu, H5N1, or Avian Flu could become a Pandemic; Maybe! The question is will it mutate into a form that can spread quickly and easily.

Or should we all as the Scouts say - "Be Prepared"
